We look at the division of 37143099 by 54 
The aim is to understand the frequency of 54 in 37143099.

Let's proceed to step 1:
54 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 54

Going ahead to step 2:
The number 54 fits into 37 0 times, leaving a remainder of 37.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 37 to get 37.
Bring next digit (1) of the dividend behind the 37 and repeat the process: 371 / 54

On to step 3:
If we divide 371 by 54, we get 6 and a remainder of 47.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we take 324 away from 371, we end up with 47.
Take the next digit (4) from the dividend and append it to 47, then repeat: 474 / 54

Step 4:
54 can be fit into 474 8 times, resulting in a remainder of 42.
The number 8 becomes the next digit in our result. 
Result so far: 68.0
Subtracting 432 from 474 leaves us with 42.
Grab the next digit (3) from the dividend, add it to 42, then carry on: 423 / 54

Advancing to step 5:
When dividing 423 by 54, we get 7 with a remainder of 45.
Record the quotient 7 as the next digit in the result. 
Result so far: 687.0
Subtracting 378 from 423 leaves us with 45.
Take the next digit (0) from the dividend and append it to 45, then repeat: 450 / 54

Step 6:
If we divide 450 by 54, we get 8 and a remainder of 18.
The next digit of our result is 8. 
Result so far: 6878.0
The remainder is 18 after subtracting 432 from 450.
Bring next digit (9) of the dividend behind the 18 and repeat the process: 189 / 54

Moving on to step 7:
54 goes into 189 3 times with a remainder of 27.
Use 3 as the next digit of our solution. 
Result so far: 68783.0
The remainder is 27 after subtracting 162 from 189.
Grab the next digit (9) from the dividend, add it to 27, then carry on: 279 / 54

Advancing to step 8:
When dividing 279 by 54, we get 5 with a remainder of 9.
Use 5 as the next digit of our solution. 
Result so far: 687835.0
If we subtract 270 from 279, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 9:
If we divide 90 by 54, we get 1 and a remainder of 36.
The next digit of our result is 1. 
Result so far: 687835.1
Subtract 54 from 90 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 10:
54 can be fit into 360 6 times, resulting in a remainder of 36.
The number 6 becomes the next digit in our result. 
Result so far: 687835.16
The remainder is 36 after subtracting 324 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 11:
When dividing 360 by 54, we get 6 with a remainder of 36.
Put 6 as the next digit of the answer. 
Result so far: 687835.166
If we take 324 away from 360, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Our division results in 687835.166 with a remaining 0.0036.
